Zinc(II)-operated intramolecular charge transfer fluorescence emission in pyrene-2,2′-bipyridine conjugated molecular rods
摘要:
The design and synthesis of two conjugated pyrene-2,2'-bipyridine linear rods is described. Zn(II) ion complexation allows the formation of a highly polar emissive excited state through efficient photoinduced intramolecular charge transfer. (C) 2001 Elsevier Science Ltd. AII rights reserved.

Synthesis and zinc(<scp>ii</scp>) complexation modulated fluorescence emission properties of two pyrene-oligo(phenylene vinylene)-2,2′-bipyridine conjugated molecular rods
A series of conjugated rods in which the pyrene chromophore is connected to a 2,2′-bipyridine unit via an oligo(phenylene vinylene) bridge have been synthesized and their photophysical properties in solution investigated. They are shown to display intense visible electronic absorption and fluorescence emission properties. The excited-states characteristics are compared to analogous systems containing
